Skyink 62XL Ink Cartridges Replacement for HP Envy 5540 7640

The Verdict

Are these the cartridges that finally make your HP Envy affordable to run? Let’s find out.

If you own an HP Envy 5540 or 7640, you already know the dirty secret: the printer itself is cheap, but the ink will bleed you dry. A genuine HP 62XL black cartridge runs about $45 at retail. The color? Another $50. That’s nearly a hundred bucks every time you refill. Skyink’s 62XL replacement set promises the same page yields at a fraction of the price. Here’s what you actually get.

What’s in the box

The package contains two cartridges: one black (rated 600 pages) and one tri-color (rated 300 pages). Both are the XL high-yield versions, not the standard capacity. You also get a simple instruction sheet and a pair of rubber gloves — a nice touch if you’re clumsy with ink like I am. The cartridges ship in sealed foil pouches with plastic protective caps on the print heads.

As shown in the product image, the cartridges are clearly labeled and shaped identically to the OEM HP 62XL units. The chip contacts are protected by an orange tab that needs to be pulled before installation.

Performance and real-world use

I tested these in an HP Envy 7640, printing a mix of text documents, color graphs, and photo prints on standard copy paper. Installation was straightforward — the printer recognized both cartridges immediately with no error messages or “non-genuine” warnings. That’s the biggest fear with third-party ink, and Skyink handles it well.

Text quality is sharp and dark, with no smudging or streaking on plain paper. Black density is comparable to OEM — maybe 95% of the way there. For everyday documents, you won’t notice a difference.

Color output is where things get interesting. Bright colors like blues and greens look vibrant and accurate. But skin tones and reds run slightly warm — a bit more orange than true red. One Amazon reviewer put it this way: “Photos come out looking like they have a slight Instagram filter on them. Fine for school projects, but I wouldn’t print family portraits with these.” That’s fair. For documents and charts, you’ll never notice. For photo printing, you’ll want to stick with genuine HP cartridges.

What buyers consistently praise

Across the 204 ratings (4.1 stars average), the recurring themes are value and reliability. Multiple reviewers mention getting 500+ pages from the black cartridge before needing a replacement — right in line with the XL rating. One user wrote: “I’ve gone through three sets of these and never had a single clog or error. My Envy 5640 has been running nonstop for a year.”

Another common praise point is the cost savings. At typical street prices, this two-pack runs about 50-60% less than buying genuine HP XL cartridges. For a family printing school projects or a home office churning out invoices, that adds up fast.

Where it falls short

The color accuracy issue is the main tradeoff. If you print photos regularly, this is not your cartridge. The warm cast is consistent across units, not a defect — it’s a characteristic of the ink formulation.

The protective tab removal is another minor annoyance. A few reviewers reported that pulling the tab at an angle caused slight ink leakage around the print head. It’s a small percentage of units, but worth mentioning. Pull the tab straight off, slowly, and you’ll be fine.

Battery life of the chips is also a potential concern. Skyink’s chips are designed to report ink levels, but some users noted that the printer shows “low ink” warnings earlier than with OEM cartridges — sometimes with 15-20% of ink remaining. The printer will still function, but you’ll see the warning light sooner than you’d like.

Who should buy these

• Home users with a 5540, 7640, 5660, or 5640 who print mostly documents and occasional school projects — this is a no-brainer.
• Students on a budget who need reliable printing for assignments and don’t care about photo quality.
• Small office users who go through ink quickly and want to cut consumable costs by half.

Skip them if you’re a photographer or scrapbooker who prints photos regularly. The color cast will frustrate you. Also skip if you’re not comfortable with the occasional early low-ink warning — that’s the cost of saving money.

FAQ

Q: Will these damage my HP printer? A: No. Third-party cartridges are widely used and do not cause damage. The worst-case scenario is a firmware update from HP that temporarily blocks recognition — but Skyink’s chips have been updated to work with current firmware, and the majority of recent reviews report no issues.

Q: How many pages will I actually get? A: Realistically, expect 450-550 pages from the black cartridge with standard text documents. The 600-page rating assumes 5% coverage, which is less than most people actually print. Still, that’s solid performance for the price.

Q: Do these work with HP Instant Ink? A: No. Instant Ink requires genuine HP cartridges with special chips. These are for standard ink purchases only.

The Verdict

Buy it if you want to cut your printing costs significantly and your printing is documents-first. Skip it if photo quality is non-negotiable or you’re allergic to the occasional firmware hiccup that plagues all third-party ink.

At 4.2/5 stars, these are a solid value play. You’re trading a little color accuracy for a lot of savings — and for most home users, that’s a good trade.
